针对船舶机舱无线传感器网络能量高效覆盖问题，提出一种带有环形拓扑结构的小生境粒子群算法。算法应用环形邻居拓扑结构，无需设置任何小生境参数，自发形成小生境。该算法可合理有效地调动传感器节点以节省能量。仿真结果表明，改进算法在解决机舱能量高效覆盖问题上优于其他几种算法，有效延长了网络的生命周期。

The paper proposed a niching particle swarm opti-mization with a ring topology ( NPSO-RT) to solve the energy efficient coverage ( EEC ) problem in ship engine room .The algorithm used a ring neighborhood topology , which did not require any niching parameters .Therefore, it is necessary to schedule the activities of the devices in a WSN to save the network’ s limited energy .Simulation results verify the better effectiveness of the NPSO-RT for solving the EEC problem in comparison with other algorithms and prolong the lifetime .
